CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 15/011,096, filed Jan. 29, 2016. U.S. application Ser. No. 15/011,096 is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates generally to systems and methods for order filling, and relates more particularly to systems to organize orders, determine order pick lists, and update the order pick lists, and related methods.

BACKGROUND

Currently, orders for items or products placed online through an electronic commerce website (eCommerce) can be filled by being picked in a warehouse, store, or distribution center. For these orders, picking is typically performed manually by people who are referred to as pickers. Typically, each picker loads a pick list that consists of multiple items. Once the picker reaches the location of an item on the pick list, the picker either picks the item from the shelf and marked the item as “picked” on the pick list, or if the item is not available, the picker marks the item as “null” on the pick list. When the picker goes to a location and that item is not available, the picking time required to complete the pick list is unnecessarily lengthened. Furthermore, when the same unavailable item is present in more than one pick list for more than one picker, a lot of time can be wasted. Accordingly, there is a need for systems and methods to provide better order filling for items in a pick list.
